Check out this youtube video about word roots !
Some English words come from other languages such as Latin or Greek. If you know some \”root\” words and possible prefixes/suffixes, you will be able to understand the meaning of many words that are new to you. Here is an example of how you can use information to understand the meaning of a word:
Root \” predict\” ( to say before)
Suffix \” able\” ( capable of )
New word \” predictable\” ( capable of saying before)
